Designation:A395/A395M99(Reapproved 2014)Standard Specification forFerritic Ductile Iron Pressure-Retaining Castings for Use atElevated Temperatures1This standard is issued under the fixed designation A395/A395M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope1.1 This specification covers ductile iron castings forpressure-retaining parts for use at elevated temperatures.Cast-ings of all grades are suitable for use up to 450F.Fortemperatures above 450F and up to 650F,only Grade604018 castings are suitable(Note 1).1.2 Valves,flanges,pipe fittings,pumps,and other pipingcomponents are generally manufactured in advance and sup-plied from stock by the manufacturer,jobber,or dealer.1.3 For supplemental casting requirements,SpecificationA834 may be utilized.1.4 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.NOTE1For service other than as specified in this section,referenceshould be made to Specification A536 for Ductile Iron Castings.22.Referenced Documents2.1 ASTM Standards:2A247 Test Method for Evaluating the Microstructure ofGraphite in Iron CastingsA370 Test Methods and Definitions for Mechanical Testingof Steel ProductsA536 Specification for Ductile Iron CastingsA732/A732M Specification for Castings,Investment,Car-bon and Low Alloy Steel for General Application,andCobalt Alloy for High Strength at Elevated TemperaturesA834 Specification for Common Requirements for IronCastings for General Industrial UseE8 Test Methods for Tension Testing of Metallic MaterialsE10 Test Method for Brinell Hardness of Metallic MaterialsE186 Reference Radiographs for Heavy-Walled(2 to 412-in.(50.8 to 114-mm)Steel CastingsE280 Reference Radiographs for Heavy-Walled(412to 12-in.(114 to 305-mm)Steel CastingsE446 Reference Radiographs for Steel Castings Up to 2 in.(50.8 mm)in ThicknessE689 Reference Radiographs for Ductile Iron CastingsE1806 Practice for Sampling Steel and Iron for Determina-tion of Chemical CompositionF1476 Specification for Performance of Gasketed Mechani-cal Couplings for Use in Piping ApplicationsF1548 Specification for Performance of Fittings for Use withGasketed Mechanical Couplings Used in Piping Applica-tions2.2 Manufacturers Standardization Society of the Valve andFittings Industry Standard:3SP 25 Standard Marking Systems for Valves,Flanges,PipeFittings,and Unions3.Classification3.1 Castings ordered to this specification are classified bygrades based on mechanical property requirements,as listed inTable 1.See note following Table 1.4.Ordering Information4.1 Orders for material under this specification shall includethe following applicable information:4.1.1 Drawing,catalog number,or part identifications,4.1.1.1 For grade 65-45-15,drawing indicating critical ar-ea(s)of casting(see 7.2.2 and 7.3.2).4.1.2 Quantity(weight or number of pieces),4.1.3 ASTM designation and year of issue,4.1.4 Grade(See Table 1),if a Grade is not specified,themanufacturer shall supply grade 60-40-18.1This specification is under the jurisdiction of ASTM Committee A04 on IronCastings and is the direct responsibility of Subcommittee A04.02 on Malleable andDuctile Iron Castings.Current edition approved April 1,2014.Published April 2014.Originallyapproved in 1955.Last previous edition approved in 2009 as A395/A395M 99(2009).DOI:10.1520/A0395_A0395M-99R14.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from Manufacturers Standardization Society of the Valve and FittingsIndustry(MSS),127 Park St.,NE,Vienna,VA22180-4602,http:/www.mss-hq.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.1.5 Heat-treating requirements(see 5.2.1),4.1.6 Pressure test requirements(see 7.4.3),4.1.7 Test samples from castings(see 11.1.1 and 12.1.1),4.1.8 Test coupons size(see 11.2),4.1.9 Metallographic option(see 12.1.1),4.1.10 Place of inspection(see 16.1),4.1.11 Certification requirements(see 17.1),4.1.12 Identification marking(see 18.2),and4.1.13 Supplemental Requirements(see 1.4,7.4.2,S1 andS2).5.Materials and Manufacture5.1 The melting method and the nodularizing practice shallbe optional with the foundry.5.2 Except as provided in 5.2.1,all castings Grade 60-40-18shall be given a ferritizing heat treatment that producese
